3l Claims.

This invention relates generally to `controlling mechanism for tabulating machines and .more particularly to an .automatic means for stopping thek machine when the card eject pocket is filled in order to prevent the cards from overflowing therefrom. r l. j

` The device of theA present invention is disclosed in the description to follow .as applied to a Powers type tabulating rmachine which, as is well known in the art, operates on perioratedrecord cards to tabulate the data contained on these cards. The record cards are `fed seriatim from a storage magazine into a sensing chamber where they are analyzedand from there are ejected into a receiving o-r eject pocket. l The receiving or eject pocket used in the Powers machine is of amp-le size to accommodate all of the cards which may be placed-in the .storage :magazine at `one time but it has been Iound ,that ifthe operator of the machine continues to insert successivestacks of cards into the magazine and neglects to remove the :accumulated `cards from the lejectpocket at regu- 4lar intervals, then the cards will overow from the vpocket :and drop to the floor in considerable disorder. This is lundesirableas the cards which are used in the tabulator l,are -sorted in a certain sequence which should be maintained .even after the cards are run through the machine. This is donc to permit reling zfor future use. llt `has also been found that vifvfthe :receiving lpocket is per.- .mittedto overflow, the ejection Iof the .cards from the sensing chamber is :sometimes hindered to the extent of causing jamming ef the machine.

.The device of the ypresent .invention .constitutes a means for preventing the overflow of the receiving pocket through the provisionof controlling mechanism operable by a floating :plate in the receiving pocket for effecting :an .operation fof the lregularstoppingmechanism yof the machine when the pocket 'becomes lled.

'Onenbiect of this invention is toiprovide means ior causing the machine lto vstop when the eject pocket'is filled thereby preventing thedisarrangement of .card vsequence caused by the overflow of thepocket. l

` Another object `of this invention is to provide a stopping device foperablerfrom the'freceiving pocket fof a -tab-ulating .machine .and lcooperable with the regular stopping -mechanism of the machine which l.device may be mountedy in its present embodiment on :a Powers type 'tabuiating machine, and in -other embodiments on 4any similar type of maichine.

General description closed in the U. S. patent to. William vW.` Lasker No. 2,044,119 issued June 16, 1936. The present invention is concerned chieily with certain'loase controls for the automatic stopping of the machine so that the drawings .and the description to follow are directed primarily towards the disclosure .of these controls. ForI a more complete showing .of the various operating mechanisms of the base, reference should be made to the above mentioned patent.

Accordingto the well known construction .of the Powers machine .and as is partially shown herein, the mechanism of the base is mounted upon a plate -I (see Fig. 1) and is further .supported by .the side frames 2 mounted upon the baseplate I. Situated at the front of the machine vis a .card magazine vor storage chamber 3 into which .the lcards to be tabulated .are placed. A card picker (not shown) is provided for ejecting the cards singly from the magazine 3 into position to .be picked up by a pair of power driven feed rollers 4 thereby to be fed into the sensing chamber Where the perforated data on the card is analyzed. The .sensing chamber is comprised of a perforated plate 5 supported between the side frames 2 anda -second :perforated plate (not shown) spaced `slightly below the plate 5 and rigidly secured thereto by means of screws. Each successive card is driven by the rollers 4 between the above 'two plates and continues its rearward travel under thepropulsion of two sets -of positively driven ski-d rollers 6 and 1 (one set shown) vcooperable respectively with two sets o f pressure rolls 8 and l9 (one set shown) mounted on the upper surface of the plate 5 near the opposite ends thereof and .extendling downward through openings cutin the plate.

Each pair of rolls 8 and 9 are connected bya spring Il and are thereby urged into contact with their respective pair of skid rollers '6 and .1. Normally blocking the exit of the sensingchamber is a .plate or card stop l2 which is adapted to hold the card in position for sensing in order that .the-data represented thereon may be recorded and accumulated. During the time the'card remains :in the sensing chamber limiting against the stop so y in the chamber is immediately ejected therefrom` by the sets of rolls 6 and 8, I and 9 and is positioned between still another pair of rollers |3` Which deposit the card in a receiving or eject pocket I4. The receiving pocket I4 is'of a single piece construction and is formed with side plates, a rear plate (as viewed from the rear of the machine) and a base plate but no front plate.

The rear of the pocket (as viewed from the front of the machine) is left open in order to simplify the removal of the cards therefrom. The pocket is fastened by screws to the base plate 2 and vcontains a floating plate I5 to the lower surface of which is secured the upper end of a vertical rod I6. The rod I 6 extends downwardly through the base of the pocket I4 and also through a hole in the main base plate I. Secured to the lower end of the rod I6 is a collar I'I on the upper surface of which is adhesively xed a felt strip I8 adapted to contact a collar I9 rigidly secured to the base plate of the pocket |4 and extending through an opening in the plate 2. The floating plate I5 is normally held in the position shown in Fig. 1, which is its highest vertical position, by means of a compression spring 2| fixed to the base plate I and pressing against the lower surface of the plate I5. As the cards are fed into the receiving pocket I4 by the rollers |3, they drop onto the plate I5 which extends throughout the width of the pocket. As the cards continue to be fed into the receiving pocket their accumulated weight causes the plate I5 to move downward, against the expansion of spring 2|, thereby making room for additional cards. In the machines heretofore used, not equipped with the device of the present invention, a large accumulation of cards in the receiving pocket would cause the plate I5 to be depressed until the spring 2| could no longer be compressed at which time the operator had to stop the machine and remove the cards in order to prevent the pocket from overflowing. The present invention operates in a manner to be described to stop the machine automatically before the plate I5 reaches its extreme lowered position.

Starting and stopping mechanism As disclosed in the above mentioned Patent 2,044,119 tabulating machines of the type shown herein contain certain motor operated drive mechanisms and are provided with a clutch for engaging and disengaging the motor and the drive mechanisms. The drive and clutch mechanisms employed in the present machine are not completely shown herein but may be of the same type as that shown in the above patent. Certain of the control mechanism for operating the machine clutch is shown herein however, and operates, briefly, as follows. As shown in Fig. 2 one end of a shaft 22 is loosely mounted between the side frames 2. The opposite or right hand endl of the shaft 22 controls the clutch mechanism and it is through the rocking of this shaft that the clutch is moved to engaged or disengaged position. When the shaft 22 is positioned as shown in Fig. 2 the clutch is disengaged. Clockwise movement of the shaft 22 will engage the clutch and place the machine drive mechanism under the control of the motor. Secured to the extreme left-hand end of the shaft 22 (Fig. 2) is a rearwardly extending arm 23 to which is connected certain toggle mechanism (not shown herein) mounted. on the right-hand side of a link 24 also connected vto the arm 23. The above toggle mechanism has been disclosed4 in various modied forms in numerous previous applications and patents.

The application of Elmer H. Dreher, S. N. 69,570, filed March 18, 1936, for example, describes a type of toggle mechanism applicable to the present machine, as does the application of Karl Braun, S. N. 138,699 filed April 24, 1937. The shaft 22, therefore, in the position shown in Fig. 2 is holding the clutch disengaged and so long as the toggle mechanism remains erect, or unbroken, the shaft will be held in this position. If, however, the toggle is caused to break, suitable spring tension (not shown) is provided for rocking the shaft 22 a short distance in a clockwise direction (Fig. 2) which causes the engagement of the clutch and an upward movement of link 24 to place certain elements associated therewith in operating position in a manner to be described hereinafter. Now, if at some point in the operation of the machine the link 24 is depressed it will straighten the toggle mechanism mounted thereon to rock arm'23 and thereby shaft 22 a suicient distance to `again disengage the machine clutch.

The means for causing the breaking of the toggle mechanism and the consequent engagement of the clutch lies in amanually operable push button 25 (Fig. 2) situated at the front of the machine. The button 25Vis'secured to the outer end of a rod 26, the inner end of which is connected to a rearwardly extending link 2'I which is, in turn, connected to an arm 28 pivoted to side frame 2. Connected to the upper end of the arrn 28 is a forwardly extending hook-like lever 29r cooperable with the previously mentioned toggle mechanism. When the machine is in the stopping' position the button 25 and its associated elements 26, 21, 28, and 29 occupy the position shownY in Fig. 2 due to the pressure of a coil spring (not shown) which urges the button 25 outward. If, however, the button 25 is pressed inward the result will be to rock the arm 28 a short distance in a counterclockwise direction which, through the medium of lever 29, serves to break the toggle, in a manner not herein shown to engage the clutch.

As previously mentioned the disabling of the clutch is caused by the depression of the link 24. Through means now to be described it will be seen that the link 24 may be caused to be depressed either manually, by pressing button 25 While the machine is running. or through any one of several automatic means. Still referring to Fig. '2 there is also shown therein the well known main cam shaft 3| supported between the side frames 2 and adapted to rotate in a clockwise direction (Fig. 2) as long as the clutch is engaged. Fixed to the extreme left-hand end of the shaft 3| is a cam 32 formed with a single high Vspot or bump 33. Cooperating with the cam 32 is a follower on an arm 34 pivoted to the outer end of a stud 35 fastened to the frame plate 2. Connected to the forward end of the arm 34 is an upwardly extending link 36 guided in the bent over portion of the plate 2 and having its upper end positioned just beneath a recessed portion of an interponent arm 31. The interponent arm 3'I is pivoted at its forward end to another arm 38 fast on a shaft39 loosely supported by a casting 4I secured to the plate 2. It willbe seen that the link 36 is given a vertical reciprocal motion once for each cycle of the `cam 32. It will also be seen that as long as .thearm 31 remains in the position shown in Fig.. 2 the link 36 will be unable to elevate the arm since the upper end of the link will merely move ineifectively in the recessedl portion of the arm mentioned above. If, however, the arm 31 is caused to move rearwardly by the rocking -of .arm 38 the `lower edgeof the arm will be .moved into position over the link 36 so that the next time the link is elevated the arm 31 will be rocked upward to cause the simultaneous rocking of a lever/l2 by contacting a lug `42A securedtothe rearmost end of the lever.` The lever 412 is pivoted 'at its mid-point to a stud also supported by thecasting 4I and has its forward end bent over and a set screw 43 passed therethrough. The lower end of the screw 43 bears against an arm 44 pivoted at its rearmost end to the same stud which supports lever 42, andconnected at its forward end to the upper end of thelink 24. While the machine clutch is disengaged the link 2-4 :is held depressed by reason of the erect toggle, and a spring 44A connecting the arm 44 .and lever 42 holds the lever rocked in the position shown in Fig. 2. VWhen the toggle is broken, however, the link 24 rises as previously described and rocks the lever 42 in a counterclockwise direction to bring the lug 42A into contact with the arm 31.. Therefore, if the arm 31 is shifted by link 36 as before mentioned the result `will be to rock the lever 42 in a clockwise direction thereby rocking the arm 44 in the same direction to depressfthe link 24 causing the-disengagement of the machine clutch as previously described. 'It is evident, therefore, that anything Iwhich rocks the arm 38 rearwardly will cause the stopping of the machine. This may be done manually by pressing the button 25 or automatically by rocking the shaft 29 to which the arm 38 is secured.

The arm 38 extends .downwardly through a slot in the plate 2 and its lowerv end lof a lug which is adapted to be engaged by a shoulder formed in the rearmost end of a finger-like arm 45 connected at its forward end to the previously mentioned arm 28 movable by the button 25. If, then', it is desirable to stop the machine manually the button 25 is pressed inward thereby rocking the arm 3B and positioning the shoulder on .arm 31 over the link 35. The button must then be held in operating position until the high spot 33 on cam 32 elevates the link 36 at which time the above sequence of operation takes place. "The shaft 39 which also rocks the arm 38 is, as previously mentioned, supported by a casting 4I only partially shown herein. The casting 4I also acts as a support for the automatic total-control mechanism which is standard mechanism for all Powers tabulators. The total control mechanism has been omittedfrom the present drawings and a portion of the casting 4l cutaway in order to show more clearly the control mechanism for rocking the shaft 39. As disclosed in Patent No. 2,044,119 there is provided two standard operating means for automatically stopping the machine. One means comprises a spring pressed pin projecting into the card magazine 3. While there are one or more cards presen-t vin the magazine thispin is held displaced and ineffective. When the last card leaves the magazine, however, the pin will move under tension of its spring to rock the shaft 39 and thereby stop the machine. The second standard means for-automatically stopping the machine lies Ain theprovision of a special pin in the lower pin box A(not shown). This pin rises with the lower pin y mitted 'to move to its extreme elevated position f with the pin box .and causes the rocking of shaft 39 to stop'the machine. rlfhis second means is provided in vorder to prevent a continuance of f machine operation when the cards fail to feed properly from'the magazine because of jamming or .some like occurrence;

The above automatic stop devices are partially shown herein in Figs. 1 and 2. Referring to Fig. 1 the above mentioned pin projecting into the card `magazine r3 is indicated bythe reference numeral 46 and is shown held displaced by the cards `in the magazine. The lower end of the pin 46 is connected to a lever 41 pivoted at its mid-point to a frame supported stud 48. A spring 49 tensoned between the forward end of the lever 41v and the base of the card magazine serves to urge the lever 41 in a counter-clockwise direction and the pin 46 upward. r.I'he rear end of the lever 41 is connected to a vertical link`5| connected at its upper end to an arm :52 `loosely mounted on the shaft 39. The arm 52 extends rearwardly of its pivot 39 and on its yfar end is a laterally extending stud 53 which underlies an arm-54 secured to the shaft 39. It is evident that upward motion of the pin 46 and counter-clockwise movement of the lever 41 will be transmitted through link 5I, arm 5.2 and arm 54 to the shaft 39 to rock the shaft in a clockwise direction as viewed in Fig. l. Thestop pin contained in the lower pin box is not shown herein but is adapted to cooperate with an offset rod 55 connected at its upper end to the arm '54 and 'having its lower end projecting downward through the upper chamber plate 5 (see also Fig) The stoppin is positioned directly beneath the rod `55 and if no card is in the .chamber during a sensingoperation the pin will elevate the rod to rock shaft 39 through arm 54. The weight of rod 55 and arm 54 cause shaft `39 and arm 38 to assume the normal position shown in Fig. 2. The drawings have been made onthe assumption that a card is in the sensing chamber and preventing an operation of rod 55.

Automatic stop from `receiving pocket The mechanism of the invention makes possible a third means of automatically stopping the machine, this mechanism being controlled from the receiving or eject pocket I4 and operating to rock the vshaft 39 like the two standard means described above. As shown in Fig. 2 there is mounted on the base plate l slightly to the rear and vto the right of the pocket I4 (as viewed from the rear of the machine) a plate or bracket 56. Ashouldered screw 51 is secured in the bracket 56 and pivoted on the screw 51 is a rearwardly extending lever 58. The rearmost end of the lever 58 extends through a slot 59 cut in a corner of the pocket kI4 and is formed with an upturned toe. Also pivoted on the screw 51 is a latch `61 the upper end of which normally rests beneath a'collar secured to a vertically extending rod 62 guided in a bracket 63 mounted on the left hand side frame 2. A coil spring 54 compressed between the bracket 63 and a second collar on the rod 62 serves to urge the rod downward. The upper end Aof the rod 62 is connected by means of va spring clip to the vrearrnost end Vof an arm 65 pivoted to a bracket 66 secured to the upper surface of the sensing chamber plate 5. 'Ihe arm 65 is bent inward slightly and its forward end is out away to form a finger which rests beneath the offset portion of the previously mentioned rod 55. The above chain of mechanism is shown in Fi-g. l in its normal position with the rod 62 held upward against the tension of its spring 64 by the latch 6I. Now, it will be seen that as the floating plate I descends under the weight of the accumulated cards supported thereon, the lower surface of the plate will contact the upturned toe of the lever 58 after the plate has moved a certain distance and that continued downward movement of the plate will rock the lever ina counter-clockwise direction as viewed in Fig. 1. The forward end of-lever 58 is formed with a bent over lug 61 which bears upon the edge of the latch 6I. A spring 68 tensioned between the latch 6I and the lug 6T serves to maintain the latch and lug in contact while another spring 69, tensioned betwen the bracket 56 and the lower end of lug 6l urges the lever 58 in a clockwise direction. A screw 'II set in the bracket 56 limits the distance which lever 58 may rock under tension of spring 69 and is formed with an eccentric head in order to vary the time of the levers actuation by plate I5. Returning now to the counterclockwise rocking motion imparted to the lever 58 by plate I5 it is evident that this motion will disable the latch 6I and permit the rod 82 to drop downward under tension of its spring 64. Downward motion of rod 62 causes a counter-clockwise motion (Fig. 1) of arm 55 about its pivot E6, thereby elevating rod 55 to rock the stop shaft 39. In operated position the above mechanism assumes the position shown in Fig. 3. The rocking of shaft 39 through the operation of lever 58 does not occur during any predetermined machine cycle nor at any predetermined moment during a cycle. The rod 62, when released by the disabling of latch 6I, will be held downward by spring 64 so that the shaft 39 will remain rocked until the rise 33 on cam 32 (Fig. 2) reaches cooperative relation with its follower to actuate the mechanism for disengaging the clutch. After the machine has stopped the stack of cards in the receiving pocket I4 (Fig. 1) may be removed at which time the plate I5 will rise under expansion of the spring 2I thereby relieving the pressure on lever 58 and allowing it to be returned to normal by the spring 69. However, inasmuch as the rod 62 is still held depressed by the spring 54, the latch 6I is prevented from returning to normal with the lever 58 and is held outward in ineffective position against the tension of spring 68. Now, when it is desired to start the machine again the push button 25 (Fig. 2) is pressed causing immediate engagement of the clutch and the starting of the machine. However since the rod E2 is still depressed and consequently the shaft 39 is still rocked it will be seen that unless the shaft 39 is returned to normal at some time during the first machine cycle the machine will be again stopped after one cycle of the cam 32. Therefore an automatic means is provided for restoring the rod 62 and permitting the reengagement of latch 6I during the first cycle vof operation after the machine is restarted.

Itwill be remembered that in considering the travel of the record cards through the machine, it was noted that each successive card is held in the sensing chamber for a portion of one machine cycle by the card stop I2. The stop I2 normally blocks the exit of the sensing chamber, but once for each machine cycle it is elevated for a short time to enable the card which has just been sensed to be ejected into the receiving pocket I4. The card stop is thus a reciprocating element and is controlled by a cam on the main shaft 3I. The restoration of rod 62 is accomplished in a manner now to be described by controlling mechanism intermediate of the card stop operating cam and the card stop itself. Referring now to Fig. 2 there is shown therein the card stop cam mounted on the shaft 3| and indicated by the reference numeral 12. Cooperating with the cam 'I2 is a roller bearing arm 13 pivoted at its rearmost end on a stud 'I4 xed to the left-hand frame plate 2. The forward end of the arm 'I3 is connected to an upwardly extending link I5 extending through the bent over portion of side frame 2 and connected at'its upper end to an arm 16 secured to a shaft 'I'I one end of which is loosely supported by a bracket 'F8 mounted on the lframe 2. Suitable spring tension (not shown) is provided for urging the shaft TI in a counterclockwise direction as viewed in Fig. 2. The shaft 'H is, however, normally held in the position shown in Fig. 2 by the cam 12, the high surfaceof which normally presses upon the roller on arm '13. The cam 'I2 is formed with a low spot or depression and when, in the course of rotation of shaft 3|, this low spot reaches cooperative relation with the roller on arm 13, the spring pressure exerted upon shaft TI causes the roller to move into the depression thereby permitting the shaft 17 to rock a short distance in a counter-clockwise direction. The opposite end of the shaft 'I1 (see Fig. 1) is supported in a manner not completely shown herein by a bracket I9 xed to the rear of the upper pin box. The reciprocation of shaft 'I1 is imparted to the card stop I2 through arm 8|, fast on the shaft 11, link 82 and another arm 83 fast on a shaft 84 supported at'one end by the bracket 'I9 and at its other end by another bracket (not shown) similar tol bracket 'I9 and secured to the opposite end of the upper pin box. Fixed to the opposite end of the shaft 84 is a second arm 83. The pair of arms 83 operate directly upon the card stop I2 and receive a reciprocal rocking motion from the shaft 'I'I to open and close the exit of the sensing chamber once for each cycle of the machine. Also secured to the shaft 'Il is a forwardly extending follower arm 85 (Fig. l) which heretofore has been used solely in cooperation with the card stop cam of the total unit. The purpose of this cam in the total unit is to hold the card stop closed for two complete machine cycles in order that the card which tripped the total may be retained in the sensing chamber to be positively sensed at the end of the total cycle. This function is old and well known in the Powers type machine and is fully described in the previously mentioned Patent 2,044,119 wherein Fig. 21 Vof the drawings illustrates the cam in question indicated by the numeral 385. This same cam is shown in the present case in Fig. 1 and bears the same reference numeral, 385. The cam 385 is positioned above the arm 85 and normally lies with one of its three low spots over the roller on the arm. The cam 385 is normally stationary and as long as it retains the position shown in Fig. 1, the shaft TI is free to rock and the roller on arm 85 merely moves into and out of the low spot on the cam once each machine cycle. During a total taking operation, however, the cam 385 is adapted to rotate in three step like motions, during the first two of which one of the three high spots on the cam press upon the the machine, the combination of a receiving roller on arm 85 and so prevent the reciprocation of shaft 11 and the consequent opening of the card stop. The third step of movement of cam 385 is the normalizing step of the control unit and places a low spot on the cam again above arm 85. Thus it will be seen that once each machine cycle, except vduring total taking'operations the arm 85 moves in a reciprocal rocking motion with the shaft T. Itis this motion that is utilized to restore the rod 62.

Connected to the arm 85 is a downwardly extending link 86 adjustably secured to a second link 81 connected by a pin and slot to the rearY of the previously mentioned arm 65. A pin on the arm 65 normally rests in the upper end of a slot in link 81. The lost motion provided by this pin and slot connection enables the arm 85 to be reciprocated freely Without effecting an operation of the arm 65 so long as the latter arm remains in normal position. However if the arm 65 is operated to bring about the stopping of the machine, it will be held in operating position by the rod 62 with the pin thereon resting in the lower end of the slot in link 81 as is illustrated in Fig. 4. Now, inthe course of the first cycle of operation after the machine is again started, the arm 85 will be moved upward as the card stop is raised thereby rocking the arm 65 in a counter-clockwise direction (Fig. 4) to lift the rod 62 in which position it is retained, as the latch El returns to engaging position. The weight of rod 55 and arm 54 will immediately restore shaft 39 to normal and cards is permitted to continue. It is possible that the4 machine may be stopped, through an actuation of lever 53, at the beginning of a total taking operation. If this occurs it is evident that the arm 85 will be prevented from restoring the arm 65 so that it becomes necessary to press the starting butto-n 25 two or three times in order to complete the total operation. On the rst adding cycle following the total cycle the arm 65 will be restored.

While I have described what I consider to be a highly desirable embodiment of my invention, it is obvious that many changes in form could be made without departing from the spirit of my invention, and I, therefore, do not limitrnyself to the exact form herein shown and described, nor to anything less than the Whole of my invention as hereinbefore set forth, and as hereinafter claimed.

What I claim as new, and desire to secure by Letters Patent, is:
